Armature: How to lock root bone to 0,0,0


I’m working with a makehuman armature. The root bone is at 0,0,0 (floor) and pelvis is the child bone.
For my in-place animations, I need the root bone to stick to origin, or somehow “lock” to 0,0,0, but when I
move the pelvis, the root bone is moved with it.
I see othere armatures are doing this, but I can’t find how (UE4 default manequin, mixamo, and others)
Which is the correct way of doing this?

If your root bone isn’t parented to anything it shouldn’t move when moving the pelvis.
